You can click the button for Monthly view and then click on any day to get more detailed info on the day, change the month so you can plan ahead, etc.

If you are going to a different area, you can also delete the Clear Lake off the URL and it will give you a map. Zoom in (i.e., Morgan's Point or Lynchburg Landing for Baytown) and hover over the monitoring station. A box will appear and you can see basic tide data for that day. There is also a link at the bottom of that box -- click Monthly Table from there to get to the monthly chart, etc.
